That error message says that you need to install erlang asn1 library to compile the *.asn1 file.

But you really only want to compile mod_archive_odbc.erl, not all ejabberd source code, right?. Instead of running 'make', try simply running:

$ erlc mod_archive_odbc.erl
./mod_archive_odbc.erl:71: Warning: behaviour gen_mod undefined

Don't worry about this warning. Then copy the beam file with all your other ejabberd beam files.
